What SEC filings does Group 1 Automotive, Inc. submit to the SEC?

Group 1 Automotive, Inc. (GPI) submits several types of SEC filings including Form 4 (insider transactions), Form 144 (proposed insider sales), 8-K reports (material events such as earnings releases, acquisitions, leadership changes), and periodic reports — the 10-Q (quarterly) and 10-K (annual). All filings are publicly available through SEC EDGAR.

What does a Form 4 filing tell me about GPI?

A Form 4 for GPI discloses a transaction by a company insider — typically a director, officer, or 10%+ shareholder. It shows the source-reported date, number of shares, price, and updated ownership. These facts do not establish motive or predict future returns.

How do I interpret an 8-K filing from Group 1 Automotive, Inc.?

An 8-K signals a material event requiring prompt disclosure. Common triggers include earnings pre-announcements, acquisitions, leadership appointments or departures, credit changes, or regulatory actions. Read the item codes inside the filing to understand exactly what was disclosed before drawing conclusions.

What is the difference between a 10-K and 10-Q for GPI?

The 10-K is Group 1 Automotive, Inc.'s annual report with fully audited financial statements, comprehensive MD&A, and complete risk factor disclosures — filed 60–90 days after fiscal year-end. The 10-Q is a lighter quarterly report with unaudited financials filed for the first three quarters. Together they provide a continuous financial picture of the company.

Where can I see all GPI SEC filings directly on EDGAR?

You can view all historical Group 1 Automotive, Inc. filings on the SEC EDGAR company page for GPI. Each filing card on this page links directly to the original SEC document.

How often does Group 1 Automotive, Inc. file with the SEC?

Group 1 Automotive, Inc. files one 10-K per year and up to three 10-Qs per year. Form 4 insider transactions must be reported within two business days of each trade, so the frequency depends on how often insiders are buying or selling GPI shares. 8-K filings occur whenever a material event happens — which can be several times per quarter for an active company.

Conifer Management, L.L.C. (10% Owner) · 2026-09-30

273,712 shares · Form 4

Insider Transactions 10 · Forms 3, 4 and 5

A Form 4 is filed within two business days of a company insider — an officer, a director, or a holder of more than ten percent of the stock — changing their position in the shares. All 10 filings in this group are Form 4s for Group 1 Automotive, Inc.

The difficulty with reading these filings as a group is that a single form type covers transactions that mean entirely different things. An executive spending their own money to buy stock and an executive having shares withheld to pay tax on a vesting grant both appear as a Form 4. Every filing below is therefore tagged with the nature of the underlying transaction, taken from the transaction code reported on the form itself.

Across the 10 insider filings shown, the breakdown is 6 open-market purchase, 2 compensation award, 1 gift and 1 tax withholding. 6 of them involved a discretionary open-market trade; the rest are compensation and administrative mechanics.

What each transaction type means

Open-market purchase ×6: The insider bought shares on the open market with their own money. This is the only Form 4 category that requires a discretionary cash outlay at the prevailing price.
Compensation award ×2: Shares were granted as compensation rather than purchased. No cash changed hands, so the filing reflects a pay decision by the company, not a judgement about the price.
Gift ×1: Shares were transferred as a gift, typically for estate or charitable planning. No sale into the market took place.
Tax withholding ×1: Shares were withheld by the company to settle tax due when equity vested. This is an automatic administrative step and not a decision to sell.
